摘　　要：通过显微观察,研究了在流动注射一示差脉冲阳极溶出伏安法中,使用壁喷玻碳电极时,在不同的预镀汞膜条件下,在电极表面上形成的汞膜的状态。并获得了适宜的预镀汞膜条件。适宜的预镀汞膜条件为:。The state of mercury film on the surface of wall-jet glassy carbon electrode under different pre-plating mercury conditions in flow injection analysis-differential pulse anodic stripping voltammetry has been studied with microscope and microphotograph, and thereby suitable condition for pre-plating mercury was obtained. The suitable pre-plating condition is -1. 40 V for Ed.5× 10-5 mol/L for CHg2+ .20 min for Td,0. 32-0. 48 ml/min for u.
